Private schools across the country are training teachers to expose kids as young as four years old to sexually explicit content — in secrecy and without parents’ knowledge — directed by the National Association Independent Schools (NAIS) as part of a “queer-inclusive” curriculum.

Breitbart News has reviewed an extensive trove of NAIS documents and teacher trainings supplied to private schools nation-wide, which, under the guise of being “queer” and “LGBTQ+ inclusive,” urge the use of graphic sexual material in classes starting at Pre-K.
